PURPOSE:To advance a reagent into a tunnel, to position the reagent and to execute diagnosis by setting the inclination angle of a gantry, calculating it by an arithmetic unit, sending a calculated result to a moving device and moving a holder in a direction for which horizontal and vertical directions are combined. CONSTITUTION:The upper side, lower side rotational angle of a gantry 1 are roughly set by a driving device 12 and a holder 3 is moved by a moving device 17. Then, the beam of a projector 31 provided in the entrance of the gantry 1 is made coincident with a line, which connects the corner of the eye and an external auditory canal in a head part, and a tunnel axis 28 is made coincident with the external auditory canal. When an operating switch 21 is pushed, a move command signal is sent to an arithmetic unit 22 together with the inclination angle signal of the gentry 1 from an inclination angle encoder 20 to the arithmetic unit 22 and a pulse is sent from the arithmetic unit 22 to a horizontal move part 18 of the moving device 17. Then, the moving device 17 is horizontally moved. After that, a pulse is sent to a vertical move part 19 and the moving device is vertically moved. The holder 3 is moved in orthogonal direction to the gantry 1 and advances a head part into a tunnel 10. Moving quantity in the horizontal, vertical and composite direction is displayed in display parts 23, 24 and 25 and the moving device 17 is stopped in an optimum position.
